- a CREATE TABLE will put the COLLATE option

    after CHARSET, which appears to be part of
    MySQL's arbitrary rules regarding if it will actually
    work or not.  [ticket:2225]

  - reflecting a MySQL table will ensure that the
    options added to the Table at the table.kwargs
    level have spaces converted to underscores.
    This is a slight behavioral change specifically
    to the "mysql_default_charset" option which
    previously would not be symmetrical.
